How a Dead Animal Smell Usually Starts

When outdoor rodents such as mice, rats or squirrels target your home and decide to sneak their way in, it’s recommended to move hastily in equipping yourself with the means necessary to eliminate that fast before they create a hazardous environment with their potential for spreading disease, their unsanitary droppings and other bad contaminating habits. 

Rodent invasions carry harmful diseases, reproduce at an alarming rate, and even a small invasion of a single rodent can multiply and create a uncontrollable infestation very quickly.. Killing these trespassing rodents with a rodenticide bait can resolve one issue but unfortunately often leads to another issue. This usually occurs when the rodents who have consumed the lethal bait can’t be found after they crawl up into attics, walls, vents and ceilings where they wind up dying. 

As the dead rodents begin to decompose, the odor their dead carcasses give off can be terribly awful and very overwhelming. Thus the new objective after the death of a rodent is eliminating the dead animal smell out should be carried, because by not taking action, you will have to withstand the odor getting worse and making your home practically unlivable due to the stench. 


How long Does it Take for Dead Rat to Stop Smelling?

Once the smell starts it can take up to 3 weeks for the dead rat smell to go away, while the animal is completely decomposing.    Even if you can find and remove the dead animal, you will stil have the lingering smell for up to two weeks, so it is important to use these scent neutralizers.

How Do You Get a Dead Rat’s Smell?bad smell

There are two reasons your home might be stinking up with rat odor. One is its droppings and the other could be rat poison that caused the rat to die somewhere very warm and un-ventilated.

Rats have become sharper overtime and don’t fall for the cheese-in-the-mouse-trap trick anymore. They have figured a way to bypass the trap and you usually find that the cheese is gone while trap is still intact.

Why Do Dead Animal Carcasses Smell So Bad?

The smell which comes from rotting dead rodents is generated by a combination of various chemicals including sulfur dioxide, methane, benzene derivatives and long chain hydrocarbons. This mixture of noxious gases produces a smell that is nauseating and off putting to nearly all creatures except for perhaps vultures and filth flies. The smell of a dead animal or rodent can linger and produce an even stronger odor with the passage of time as more and more of the rotting carcass decomposes in the span of a  6-10 week period.

A Messy Home

If your living space is cluttered with many things and there is not much cleaning done regularly, then you can attract pests like rats to your home in no time. Usually, the smell of food and garbage lures them inside and they make a cozy home for themselves in your home due to having a regular source of food.

Post-Rat Cleanup

If you haven’t found the dead rat yet then be sure to look up all the cracks, crevices or small places that could shelter one. It could have gone there to hide before dying. Usually it is in the kitchen area or pantry. A dead rat can mostly be found wherever you must have put the rat poison, so it won’t take you long before you find its body.

Here is what you need to do:

Follow the Smell

As disgusting as it sounds, you have to follow the smell and see where it leads you. Take help from your trusted cat or dog because they have very acute sense of smell and can help track the rat’s body.

Sealable bags

Wear some gloves and get a resealable bag. Pick the dead rat up from its tail and quickly put it inside the bag and seal it tightly. Dispose the dead rat away in another bag and throw it in the trashcan outside.

Odor cleansing

Now it is time to cleanse the atmosphere from the smell of the rotting dead rat. Here are a few ways you can use to get rid of the stench:


Get some ground coffee or pure coffee beans and place them in all the areas where you find the smell coming from. The ground coffee should be placed in plastic bowls while the beans can be scattered. It is best to use ground coffee because you don’t want any kid or pet trying to swallow them. Pure coffee has a really strong smell so it will mask off and dissipate the smell of the dead rat in no time.

Odor Removing Bags

You can buy odor removing bags from any DIY store or online. They are absorbents and will remove the stench of the dead rat in no time. Just hang the odor absorbing bags in the area where the smell is coming and it will be gone in as little as few days. The bags can also be placed farther away from the smell and still work just fine.

Diffusers and Humidifiers

Get a good diffuser or humidifier and put in some strong essential oils in it. The vapors that will be released in the air will carry the fragrance of the essential oils all around the area. Orange, peppermint, ylang ylang, lavender and bergamot are some really good essential oils that can mask any smell. You need to make the water in the humidifier more concentrated by adding twice or thrice as much of the essential oils to get rid of the dead rat’s smell from your home.

Air Ionizers

These are really effective in removing all the types of odor in a home and can even work in really big spaces. The best part about using ionizers is that they eliminate germs, dust, and allergens from the area as well.


If you think there could be more rodents lurking about your home or some other pests trying to make some shelter for themselves inside then it is a good idea to just get your entire house fumigated.

You can spray your home with bug sprays or rodent killing poison and leave your house for a day or two.

Strong Air Fresheners

Spraying the entire area with a good floral air freshener can get rid of the dead rats smell easily if the rat’s body wasn’t around for long to begin with. Spray everyday and in a few days it will all be gone.

How To Prevent a Dead Rat’s Smell

  • The only way you can prevent a dead rat’s smell is to not have any rats in the first place. Just ensure that your doors or windows are not always open.

  • The cracks and crevices are filled so that nothing can find a home there.

In the case that you weren’t even aware of a dead rodent or animal in or around your property until you noticed the odor, locating the offending create may not be an easy task. 

This is when you should sniff around and  follow your nose so to speak. As stinky as a job it may be, you will have to sniff around until you find the part of your home where the odor is the most profound. Another thing you can look for at the same time is for any stains or markings since carcasses often leak fluid as it dries out 

Another sign of where the dead carcass can be is the presences of insects since the decomposing bodies attract a slew of different bugs. Observe any insect activity, for instance, flies hanging around a wall or vent. This will be an indicator of where the dead carcass is.

This step must be acted upon quickly because the odor is only going to get worse as time passes and it may get to the point where staying in the home may be unbearable or a hazard to your well-being.

An alternative odor eliminating product we have are Earth Care Odor Removal Bag. This product is essential a bag that can be activated by being hung up in the area where the smell is the strongest and as the air in the room passes through the bag, the bag absorbs the foul smelling odor like a sponge. You can then simply dispose of the bag. A similar product is the Nature's Air Sponge Odor Eliminator.

What to do when the Dead Carcass Cannot Be Removed

There are times when the dead animal carcass cannot be reached and remove properly. In cases such as these, you usually have no choice but to wait for the rotting body to completely decompose which takes anywhere from 6-8 weeks. In the mean time you can mitigate the effects of the decomposing odor using odor eliminating products until the process has completed. Products like the Earth Care Odor Removal Bag can be placed in the area where the smell is the strongest or one of our other odor neutralizing products. 

When determining what odor removal products would be best, the size of the offending animal should be considered. The bigger the deal animal is, the stronger the odor they give off will be and the longer the odor will linger in the air. Using a combination of products is usually the best way to achieve relief until the animal is completely decomposed.

If there is a fly problem due to the dead carcass, you may have to tolerate it because the filth flies and other bugs are eating away the dead flesh so they are actually helping to clean up and rid the body faster. If they linger around after the odor is gone and the animal carcass is no more, that’s when you should seek out a control program to eliminate the bugs.
